Network Security Configuration (Questions 1-50)

Question 1 (PBQ) You are configuring a pfSense firewall for a small medical practice. Create firewall rules that:

• Allow HTTPS traffic from internal network (192.168.1.0/24) to external websites
• Block all HTTP traffic to prevent unencrypted web browsing
• Allow DNS queries from internal network to Google DNS (8.8.8.8)
• Log all denied traffic attempts

Answer:

1. Create rule: Source 192.168.1.0/24, Destination Any, Port 443, Protocol TCP, Action Allow
2. Create rule: Source 192.168.1.0/24, Destination Any, Port 80, Protocol TCP, Action Block, Log Yes
3. Create rule: Source 192.168.1.0/24, Destination 8.8.8.8, Port 53, Protocol UDP, Action Allow
4. Enable logging on default deny rule

Explanation: This configuration enforces encrypted web browsing while allowing necessary DNS resolution. Blocking HTTP prevents accidental transmission of sensitive medical data over unencrypted connections, which is crucial for HIPAA compliance.

Question 2 (PBQ) Configure a Cisco ASA firewall to implement a DMZ network. The topology includes:

• Outside interface: 203.0.113.1/24 (Internet)
• DMZ interface: 10.1.1.1/24 (Web servers)
• Inside interface: 192.168.1.1/24 (Internal network)

Create access-lists that allow:

• Internet users to access web servers on ports 80 and 443
• Internal users to access DMZ web servers
• Internal users to access the Internet
• Block all other traffic

Answer:

access-list OUTSIDE_IN permit tcp any host 10.1.1.10 eq 80

access-list OUTSIDE_IN permit tcp any host 10.1.1.10 eq 443

access-list INSIDE_IN permit tcp 192.168.1.0 255.255.255.0 10.1.1.0 255.255.255.0

access-list INSIDE_IN permit tcp 192.168.1.0 255.255.255.0 any

access-group OUTSIDE_IN in interface outside

access-group INSIDE_IN in interface inside

Explanation: DMZ configuration creates a buffer zone between Internet and internal networks. Web servers in DMZ can be accessed from Internet while internal network remains protected. This follows defense-in-depth principles.

Question 3 (PBQ) You discover that users on VLAN 10 (192.168.10.0/24) can communicate with users on VLAN 20 (192.168.20.0/24), but they should be isolated. Configure inter-VLAN access control to:

• Block all traffic between VLAN 10 and VLAN 20
• Allow both VLANs to access the Internet
• Allow both VLANs to access DNS server at 192.168.1.10
• Maintain access to default gateway

Answer:

ip access-list extended VLAN10_ACL

deny ip 192.168.10.0 0.0.0.255 192.168.20.0 0.0.0.255

permit tcp 192.168.10.0 0.0.0.255 host 192.168.1.10 eq 53

permit udp 192.168.10.0 0.0.0.255 host 192.168.1.10 eq 53

permit ip 192.168.10.0 0.0.0.255 any

ip access-list extended VLAN20_ACL

deny ip 192.168.20.0 0.0.0.255 192.168.10.0 0.0.0.255

permit tcp 192.168.20.0 0.0.0.255 host 192.168.1.10 eq 53

permit udp 192.168.20.0 0.0.0.255 host 192.168.1.10 eq 53

permit ip 192.168.20.0 0.0.0.255 any

Explanation: Access control lists prevent lateral movement between VLANs while maintaining necessary services. DNS access is explicitly permitted before the general Internet access rule to ensure name resolution works properly.

Question 4 (PBQ) Configure a Windows Defender Firewall with Advanced Security to secure a web server. Create rules that:

• Allow HTTP (port 80) and HTTPS (port 443) inbound from any source
• Allow RDP (port 3389) inbound from management network (10.0.0.0/8) only
• Block all other inbound traffic
• Allow all outbound traffic for updates and DNS

Answer:

1. Create Inbound Rule: Port 80, TCP, Allow, All Programs, Any IP
2. Create Inbound Rule: Port 443, TCP, Allow, All Programs, Any IP
3. Create Inbound Rule: Port 3389, TCP, Allow, All Programs, Scope: 10.0.0.0/8
4. Set Default Inbound Action: Block
5. Set Default Outbound Action: Allow

Explanation: This configuration follows the principle of least privilege by allowing only necessary services while restricting administrative access to the management network. Default deny for inbound traffic prevents unauthorized access attempts.

Question 5 (PBQ) A company needs to segment their network to comply with PCI DSS requirements. Configure network segmentation for:

• Cardholder Data Environment (CDE): 10.10.10.0/24
• Corporate network: 192.168.1.0/24
• Guest network: 172.16.1.0/24

Requirements:

• CDE should only communicate with specific payment processing servers
• Corporate network cannot access CDE
• Guest network cannot access any internal networks
• All networks can access Internet through proxy at 192.168.1.100

Answer:

# CDE ACL

access-list CDE_OUT permit tcp 10.10.10.0 0.0.0.255 host 203.0.113.50 eq 443

access-list CDE_OUT permit tcp 10.10.10.0 0.0.0.255 host 192.168.1.100 eq 8080

access-list CDE_OUT deny ip 10.10.10.0 0.0.0.255 any

# Corporate ACL

access-list CORP_OUT deny ip 192.168.1.0 0.0.0.255 10.10.10.0 0.0.0.255

access-list CORP_OUT permit ip 192.168.1.0 0.0.0.255 any

# Guest ACL

access-list GUEST_OUT deny ip 172.16.1.0 0.0.0.255 10.0.0.0 0.255.255.255

access-list GUEST_OUT deny ip 172.16.1.0 0.0.0.255 192.168.0.0 0.0.255.255

access-list GUEST_OUT permit tcp 172.16.1.0 0.0.0.255 host 192.168.1.100 eq 8080

Explanation: PCI DSS requires strict network segmentation to protect cardholder data. The CDE is isolated with only necessary payment processing communication allowed. This reduces the scope of PCI compliance requirements.

Question 6 (PBQ) Configure NAT (Network Address Translation) on a router to:

• Translate internal network 192.168.100.0/24 to public IP 203.0.113.10
• Create static NAT for internal web server 192.168.100.50 to public IP 203.0.113.11
• Create port forwarding for internal SSH server at 192.168.100.20:22 to public IP 203.0.113.10:2222

Answer:

# Dynamic NAT pool

ip nat pool PUBLIC_POOL 203.0.113.10 203.0.113.10 netmask 255.255.255.0

ip nat inside source list 100 pool PUBLIC_POOL overload

# Static NAT for web server

ip nat inside source static 192.168.100.50 203.0.113.11

# Port forwarding for SSH

ip nat inside source static tcp 192.168.100.20 22 203.0.113.10 2222

# Access list for internal network

access-list 100 permit ip 192.168.100.0 0.0.0.255 any

# Interface configuration

interface FastEthernet0/0

ip nat outside

interface FastEthernet0/1

ip nat inside

Explanation: NAT configuration provides Internet access for internal hosts while hiding internal network structure. Static NAT enables external access to specific servers while port forwarding allows secure remote administration on non-standard ports.

Question 7 (PBQ) Configure a site-to-site VPN between two offices using IPSec. Configure the following parameters:

• Office A: 192.168.1.0/24, Public IP: 203.0.113.1
• Office B: 192.168.2.0/24, Public IP: 203.0.113.2
• Use PSK authentication with key "SecureVPN123!"
• Use AES-256 encryption and SHA-256 hashing
• Create appropriate tunnel and transport policies

Answer:

# IKE Policy

crypto isakmp policy 10

encryption aes 256

hash sha256

authentication pre-share

group 14

# Pre-shared key

crypto isakmp key SecureVPN123! address 203.0.113.2

# IPSec transform set

crypto ipsec transform-set VPN_SET esp-aes 256 esp-sha256-hmac

# Access list for interesting traffic

access-list 101 permit ip 192.168.1.0 0.0.0.255 192.168.2.0 0.0.0.255

# Crypto map

crypto map VPN_MAP 10 ipsec-isakmp

set peer 203.0.113.2

set transform-set VPN_SET

match address 101

# Apply to interface

interface Serial0/0

crypto map VPN_MAP

Explanation: Site-to-site VPN creates secure communication between offices over the Internet. Strong encryption (AES-256) and hashing (SHA-256) ensure data confidentiality and integrity during transmission.

Question 8 (PBQ) Configure Quality of Service (QoS) on a router to prioritize...
